SEWING-MACHINE ATTACHMENT.

Specification of Letters Patent.

Patented Mar. 25, 1.919.

Application led August 27` 1917. Serial No. 138,514.

This `invention relates to lubricatingandcooling attachments for sewingmachines, such as described in my co-fpending application Serial No.180,091, filed July 12, 1917,

- and it has for its object to provide certain improvementswhch areembodied in the attachment shown on the accompanying drawing, describedin the following specification and pointed out in the appended claims.

On the drawings,-

Figure 1 illustrates, conventionally, a. sew. ing machine provided withmy improved lubricating attachment. Fig. 2 illustrates the attachment inelevation looking from the right as shown in Fig. 1, the valve casingbeing. shown partially in section, and the needle bar being raised.

Fig. 3 represents a front elevation of the same. Y

Fig. 4 represents a plan view thereof.

Fig. 5 represents the attachment with the needle bar in its lowestposition.

My improved attachment is illustrated as mounted upon a Singermachine,the latter having the needle bar 10,' the needle 11, the presserbar 12, and the rotatable flanged presser-foot disk 13, the lattercoperating with the feed 14. ln this machine the needle bar operatesthrough a'relatively long vertical path,.whereas the presser bar has ashort vertical movement, as ordinarily.

My attachment comprises a lubricant or wick holder 15 disposed in thepath of the needle and having a through aperture for the passagethereof, and motion-reducing mechanism operated by the imparting arelatively short vertical movement to the holder so as intermittently tolift it from the work to permit the latter to be fed. The holdercomprises a tube having one end closed and attened, as shown in Fig. 5,with a needle receiving' aperture 16 through the top and bottom wallsthereof. The body of the tube is inclined from the horizontal, but itsend is slightly bent so as needle bar for to lie substantially parallelwith the bed plate 17 when it is in its lowest position. Within theholder there is an absorbent wick 18 (for the lubricant) preferablyconsisting of a body of sponge' incased incheesecloth, linen, cotton, orother textile material. Be# tween its ends the holder has an opening 19into which the lubricant is dropped from a reservoir. Near its outer endthe holder is pivotally mounted upon a screw pin 20 which proJectslaterally from an ear v21 depending from a supporting plate 22. Saidplate is secured by a bolt 23 to a lug 24 which forms a part of thebracket 25 on which the arm 26 for the presser disk 13 is mounted. Thebradket is secured to the presser bar 12` so that the plate 22 rises andfalls therewith, and consequently the wick holderis moved bodily up anddown as the presser bar is reciprocated. ln addition to said bodilymovement, however, the wick holder is oscillated about the pivot 20,and, to` secure this movement, I employ a lever 27 pivoted to said plate22. 'Said lever is pivoted near one end and has a short arm pivotallyconnected by a link 28 with the outer or rear end of the wick holder,and a long arm pivoted to the lower end of the needle bar. As

'a result of thisA construction and arrange- The lubricant is containedin a reservoir 29 which is cylindrical in shape with' a removable cover30. Said reservoir issupported bythe plate- 22, and has a communicatingvalve casing 32,y in which plays a plunger valve 33. The' lower end ofthe valve casing is directly over the hole 19 to drop the lubricantthereinto when the valve is opened. The valve is reciprocated by a bar34 pivoted at 35 to the long arm of lever 27, and having an end 36apertured to receive the end of the valve plunger. A nut 37 on the upperthreaded end of said plunger is engaged by the bar, when it reaches apoint near its upper limit of movement, and lifted to raise the valveand permit a drop O f lubricant to fall into the wick holder.

The details of the -construction which I have herein described may bevaried con# arranged in the path of the needle, and

means for connecting the said holder to the needle bar for moving saidholder-in lines longitudinal of the path of the needle.

2. Anl attachment for sewin machmes,

comprising a lubricant holder a apted tov be arranged in the path 'ofthe needle, and having a through aperature for the needle,

means for pivotally supporting said holder,

and means for connecting said holder with the needle bar whereby latedby the needle bar.

3. An attachment for sewing machines, comprising a lubricant holderadapted to -be arranged inthe path of the needle and having a throughaperture for the-needle, means for pivotally supporting said holder uponsaid holder isoscilthe presser bar, and means for connecting said holderwith'the needle bar.

4. Asewing machine comprising a needle, a-needle bar, and a presser bar,in combina'- tion with a lubricant holder having-an end located below'-the needle bar ,and arranged to supply lubricant to the needle, meansfor movably supporting said holder, and motionplate, a needle andaneedle reducmg means connected to the holder and to the needle bar, -byAwhich the holder is moved with the needle toward and l-from the workbut through a shorter path of movement.

. 6. A sewing machine comprising a needle,

a needle bar, and a presser bar, in combinal tion with a lubricantholder having an end located below the needle bar and arranged to supplylubricant to the needle, a support connected to the presser bar, a pivotmember connecting the holder to the support, and an plate, Va needle anda needle v and the needle bar,

operating lever to the` needle bar and holder to cause the said 'end ofthe holder to reciprocate in approm'mate parallelism with the needle.'

7. A sewing machine comprisingv a'needle, a needle bar, and a presserbar, m-combmav .tion with a lubricant holder having an end located belowthe needle bar and arranged to supply lubricant to the needle, a supportconnected to the presser bar, a plvot mem" berV connecting the holder tothe support, an operating lever pivoted to said support, a
